This is the best I could find with a lot of weight. Like most, we ride with stock ballast if only a few bodies in the boat. With this many I don't fill any ballast as an intermediate. This advanced rider wanted all we had so 11 people with stock ballast. It was massive. I have the 5.7 and this is the only time it ever struggled. I dropped to 1/2 ballast and it did just fine. The wake was a little washy at 80 ft back if I remember right. I didn't have the ideal speed/weight distribution figured out though since I never run this much weight. Every other time pulling, smooth at all speeds.
